What is a crypto-asset exchange?
Could you elaborate on what a crypto-asset exchange is? As I understand, it plays a pivotal role in the cryptocurrency ecosystem, but I'm curious about its specific functions and operations. Is it simply a platform where digital currencies are bought and sold? Or does it offer more advanced services such as margin trading, futures contracts, or even decentralized lending? Additionally, what are the key factors to consider when choosing a crypto-asset exchange, such as security, liquidity, and supported cryptocurrencies? Understanding these aspects would help me make an informed decision in navigating the volatile yet exciting world of cryptocurrency trading.
